Inline File Validation With Uri - IBM Aspera HST Admin Manual

4. If you schedule validation at a file size threshold, set the threshold.
# asconfigurator -x
"set_user_data;user_name,username;validation_threshold_kb,size"
5. Configure multi-threaded validation.
By default, inline validation is set to use 5 threads.
If the number of validation threads is not set to 1, then multiple threads may perform different types
of validations for different (or the same) files at the same time. In such a situation, the response of
a validation_file_stop at the end of a file download might come before the response of a
validation_threshold for the same file.
To set the number of validation threads, run the following command:
# asconfigurator -x
"set_user_data;user_name,username;validation_threads,number"
For more information about the configuration parameters, see
(defining values in aspera.conf)
For more information on the output of your inline validation, see

Inline File Validation with URI

Inline file validation with URI can be customized to filter which files are validated.
Validation Requests and Returned Responses
During the inline validation process, ascp automatically generates a JSON-based request. The call is made with the
URL defined in aspera.conf. For example:
POST URL/validation/files HTTP/1.1
Content-type: application/json
The system then generates a JSON accepted or error response (OK or Bad Request). If a file validation fails, it
terminates the session with an error message from the URI.
• Sample JSON accepted response: The "file_encryption" field is only returned if server-side EAR is
present.
HTTP 200 OK
{
"id" : "1111-2222-333",
"file_encryption" : {
"passphrase" : "supersecret"
}
"aspera_response_object_name" : {
"startstop" : "start"
"xfer_id" : "AAAA-BBBB",
.
"file_csum" : "a1000abf882",
"file_csum_type" : "sha2-256"
}
}
• Sample JSON error response:
HTTP 400 Bad Request
